Sounds like you've either got a stiff motor or gunk in the drum making it difficult for the motor to turn. When the fuse blows the drum won't turn at all but as yours is trying to turn then throwing the fault up it sounds like something is causing too much resistance

    take the rear cover off and try turning the drum by hand

  • Anonymous Aug 26, 2011

    will try that tomorrow, it turns perfectly from the front though but just wondering if new machine time or call dyson ? im a gas engineer so no probs testing appliances and resistances etc

    if yours still contrarotates it may me worth checking the rack and pinion style gears are working properly which you can see on the rear of the drum with the panel removed. It has a microswitch activated by each end of the 'rack' and may cause drag if it sn't fully one way or the other. You can move it by hand, one way makes the drums spin together the other way makes them contrarotate.

    it appears to cut out when its about to spin fully or rotate oposite direction ?

  • Anonymous Aug 26, 2011

    hmmm... unplug it, take the rear cover off, push the 'rack' of the rack and pinion type gear set across to its opposite position then try turning the drum by hand. This should make the drums contrarotate which may be the cause of the excessive drag.

    just opened up the rack seems to move across ok, tried moving it opposite direction and contrarotate all seem ok although a lot stiffer then on 1 direction but i would think this is normal ? ive tried to reset and put on spin only and initiallythe gear moves over to left the drum moves a few times then makes a loud squeek and ***** down and goes onto f11 fault, possibly when its due to speed up which may suggest to me one of the motors are faulty, not sure cost of dyson but im begining to think its a component fault and as well calling them out, could try a resistance check on motors but theres about 5 cables goin into each !

  • Anonymous Aug 28, 2011

    also just removing both wiring looms to each motor 1 at a time, removed right hand motor nothing turns no noise f11 fault appears, remove left hand motor nothing turns f7 fault, thought maybe it would turn on one but not the other to easilly identify motor fault but nope nothing

  • Anonymous Aug 28, 2011

    its possible, have you tried turning the motors by hand seperately to see if ones noticably harder to turn? to be fair if it still contrarotates its worth getting dyson to fix the fault as they'll update the firmware to stop it contrarotating which will make your bearings last longer.

  • Anonymous Aug 28, 2011

    I think i'll give them a call, could change motor and could be something else its hard to tell gears seem ok etc, think its a motor as it just suddenly shuts down sharply tho but as there are two and i dont know sequence of operation then i could be spending money on the wrong thing !

GWL11 washer not draining

That fault code is 37.
Disconnect from power & Bail out all the water you can before removing pump.
Here is some info on fault 37
37. (00100101) Pump Blocked Error (No change in the water level)
While draining, the water level reading from the pressure sensor has not changed for over 3
minutes. There are three likely reasons for this fault. One is that the drain hose or the
pressure switch hose has been squashed or kinked and the pump out rate has been
dramatically reduced. The second possibility is that the pump is partially or fully blocked.
The third is that the pump is not operating due to Motor Control Module, wiring or pump
failure. This fault could also appear if the machine is pumping to an unusually high head of
drain hose or into an extended length of drain hose. The fourth possibility is a diverter
valve fault or blockage, water level is not altering as the diverter is stuck in the recirculation
mode, giving the module the appearance the pump is not lowering the water level.
Primary Source: Pump System.
Action: 1) Check that the drain hose has not been kinked.
2) Check the length of the drain hose and try to reduce the length if
excessively long. A 1-metre extension hose of the same diameter
fitted to the existing drain hose is the maximum allowable length.
3) Check for open circuit windings in the pump. (Note: Pumps are
fitted with a thermal cut-out, which will reset on cooling.)
4) If the bowl is empty of water, remove the pump from the pump
housing and check that it is not blocked. Also check the drain
hose is not blocked.
5) If the bowl contains water, then service the pump from the top of
the machine by removing the top deck and inner bowl. Bail out the
water, remove the pump cap and hood and clear the restriction.
Secondary Source: Wiring.
Action: 1) Check the pump harness is connected correctly to the pump.
2) Check continuity of the pump harness.
Tertiary Source: Motor Control Module.
Action: Activate the pump by operating the machine in spin mode. Check the
pump is rotating. If it is not operating, and Primary and Secondary
checks have been performed, then replace the Motor Control Module.

Water remains in machine. Machine stops after a minute or so and diplays F11.

F11 means Drainage fault.

Water present in appliance and is not being drained off. The display shows Drain fault F11. The buzzer is activated for 2 minutes.

Background information:
After each drain pump step, the circulation pump operates for 2 seconds and heater pressure switch B1/13 checks the water level. If it is too high (large quantity of residual water remaining in the cabinet), the drainage time is extended. If, after a further check, the water level is still too high, then the program is interrupted, the fault code is saved and the drain pump is activated. Fault code F11 is also registered if heater relay 1K1 is not activated after the fault code F51 register check; see Section 080-3.18. Drain hose kinked. Remedy: Check the drain hose for correct positioning.

Cause: Drain blocked.
Remedy:
1. Clean the on-site drain.
2. Check the sump drain.
3. Check the filters.
4. Check the heater pressure switch and replace it if necessary.

Cause: Ball in non-return valve in sump has not opened (e.g., jammed).
Remedy:
Clean the non-return valve in the sump or replace it if necessary. Cause: Foreign objects in the drain pump.

Remedy:
Clean the drain pump and its impeller.

Cause: Drain pump defective.
Remedy:
1. Check the voltage supply to the drain pump.
2. If correct voltage is present, check the drain pump motor winding.
3. Replace the drain pump, if necessary.

Cause: Foreign objects in heater pressure switch.
Remedy:
Check the heater pressure switch for blockages and correct switching point.

Cause: Heater relay defective. Heater relay (coil or contacts) becomes defective during the drainage step (after fault code F51 register check).
Remedy:
Replace the heater relay.


Hope this helps to solve it.

Have just bought a secondhand Miele G7859 dishwasher. When turning on to any programme, it shows F11 fault code and beeps. I'll happily work through any suggestions! Thanks in advance Andy

In other cases, owners found a piece of wood inside the door latch mechanism and removed it. The F11 error has not appeared since.

Hope ths helps.

Zanussi ZWF1437W E23

E23 indicates Drain pump faulty; Wiring faulty; PCB faulty.

The service information also says it should stop with the door open.



Unplug the appliance and manually remove the water via the filter or front drain point if it's fitted.

Drain it into a shallow dish, tighten the filter when you need to stop the water (or plug the hose if draining via a hose) while you empty the container.



Once empty, try the door again.

Take the filter out and clean out any debris in it.

Plug the appliance in and put the machine on a drain programe.

Listen/look at the open filter to check that the drain pump is running.
